Abstract
Various aspects of ultra-thin chip technology for flexible electronics are presented and discussed, including ultra-thin-chip fabrication, mechanical and electrical characterization, as well as chip assembly and imbedding. A stress sensor based on a stack of two ultra-thin, flexible CMOS chips indicates the particular advantages of the Chipfilm™ process technology, which is subject of this paper, when compared to other kinds of thin-chip fabrication.
